While recent research has demonstrated solid progress, this is a _very_
deep subject with many remaining difficulties. The primary issues are
best demonstrated with a few questions:
1 - What specifically constitutes pattern similarity during the matching
process? Is it a rhythmic pattern? Pitch? Are both required for
2 - How much (and in what ways) can the input deviate from the expected
pattern and still be recognizable?
3 - What type of "extra" events are allowable without damaging the
integrity of the original? For example, if 5 consecutive "extra notes"
were detected at the start of your motive would you want the system to
identify it as the original, a variation, or might it be part of a
new/different (but possibly related) idea?
Here are a few highly accomplished and respected authors on the subject.
Their research is a quick google away...
